LAS2G181MELZ40ZB

The LAS2G181MELZ40ZB is a snap-in terminal aluminum electrolytic capacitor designed for general-purpose power applications. It delivers 180 µF capacitance at a 400 V rating in a compact φ22 × 40 mm radial can, optimized for durability and elevated-temperature operation.

Built for applications where sustained ripple handling and robust high-temperature endurance matter, this part offers 2000 hours of rated performance at 105°C and RoHS compliance for regulated deployments.

Key Features

• Electrical Rating: 180 µF rated capacitance at 400 V, with a tolerance of ±20% for predictable charge storage in power circuits.
• High‑temperature Endurance: Specified lifetime of 2000 hours at 105°C, providing long-term stability under elevated operating conditions.
• Ripple and Loss Performance: Low loss angle with tanδ ≤ 0.20 (120 Hz, 20°C) and ripple current capability specified up to 1.093 A at higher frequencies, enabling effective smoothing in high-stress environments.
• Leakage Current: Low leakage current of 0.82 mA, supporting efficient energy retention and minimizing standby losses.
• Snap‑in Radial Can Package: Snap-in terminal mounting and φ22 × 40 mm can (L: 4.0 cm × D: 2.2 cm) deliver secure board retention and compact footprint for power assemblies.
• Wide Operating Range: Rated for operation from −25°C to +105°C, suitable for equipment exposed to varying ambient conditions.
• Safety Features: Designed with pressure relief vent performance to mitigate abnormal overvoltage conditions as described in the series specification.
• RoHS Compliance: Conforms to RoHS directive requirements for regulated markets.

Typical Applications

• Power Supplies: Bulk filtering and energy buffering in general-purpose AC/DC and DC/DC power supplies where 400 V rating and high-temperature endurance are required.
• Industrial Equipment: Energy smoothing and ripple suppression in industrial power electronics and equipment that operate in fluctuating-voltage environments.
• Converter and Inverter Systems: DC link and smoothing applications that benefit from the capacitor's high ripple-current capability and 105°C endurance.

Unique Advantages

• High Voltage Handling: 400 V rated voltage supports use in higher-voltage power rails without derating system design.
• Extended High‑Temperature Life: 2000 hours at 105°C provides predictable lifespan for thermal-stressed applications.
• Robust Ripple Capability: Frequency-dependent ripple current up to 1.093 A at 10 kHz enables efficient filtering across a wide frequency range.
• Compact Snap‑in Form Factor: φ22 × 40 mm radial can with snap-in terminals balances board space efficiency with secure mechanical mounting.
• Controlled Leakage and Losses: Low leakage (0.82 mA) and tanδ ≤ 0.20 reduce waste and heating in charge-storage duties.
• Safety‑Oriented Design: Pressure-relief venting and series safety tests minimize risk under abnormal voltage conditions.
